IMPROVEMENT IN ROLLER WAGON-SKEIN.

TO ALL WHOM IT MAY CONCERN:

Be it known that we, JOHN W. MORRETT and HIRAM WATTS, of Shepherdst own, Cumberland county, Pennsylvania, have invented a new and useful Improved Roller Wagon-Skein; and we do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawings, making a part of this specification, inwhich.--

Figure 1 is a perspective view of the skein itself. Figure 2 is a perspective view of the skein, when fastened in its proper position on the lower side of the axle.

Figure 3 is an' end view of the skein when the axle on which it is fastened is inserted in thehub of the wheel. In the construction of the sliein, we take the rectangular bar, a, of iron, or any other suitable metal, of a" length, width, and thickness in proportion to the size of. the axle and wheel. A part of'this bar we emhed horizontally in the lower side of the axle h, bending it in the form of an are from m, the point at which it leaves the axle, and curves along, partiallyeuihedded in the axle-tree g, to which it is fastened by the screw f. In the part of the skein embedded in the axle It, we construct a trapezoidal gutter, in which we place the rollers 11 and e, and the trapezoidal blocks 6 and c, in the ends of which rest therollers aforementioned. Through the block 0 passes the linchpi'n m, the extremities of which are seen in the wheel a, resting against the hub at n.

The wheel 0, the'axle h, and axle-tree g, are constructed in the ordinary form, hence the skein shown in fig. 1, complete and unattached, can be applied to any kind of wagon.

The rollers d and a turn the friction of the hub n upon the axle 7, from sliding tol rolling friction. The

advantage of' this, in a saving of propelling power, is at once apparent.

What we claim, and desire to secure by Letters Patent/of the United States, is The rectangular metallic bar a, embedded in the axleJr, and curving at :v, in an are along the axle-tree g,

Y and fastened thereto by the screwf, the'rollers d and a resting their axles in the ends of the trapezoidal blocks 6 and c, which slide and are adjusted in the trape'zoidalgutter in the skein, all constricted and operating in the manner and for the purpose herein set forth. j I
